Tim,
That is interesting to know that developers are jumping ship from Matrix.
I did not know this and have based my opinion on the quality of Matrix from the viewpoint of a consumer and also from chats on their forums (which may have been more pro-Matrix for obvious reasons...)
Well, if they are all jumping ship, maybe you can send a press kit to the folks still on their roster?
I don't know too much about how you run Shrapnel but it sounds like you care and are a gamer as well as a businessman. Passion for the industry is all I can ask for and I'm confident that combination will deliver a superior product at a good price and I'll be happy and the developers will too!
Good luck and here's to all the success you can eat.
